Nov. 27, 2012You need:Clean paper / pencil“Looking Inside Cells” Chart

Warm Up:Which organelle is the gel-like stuff that organelles all swim around in? Which organelle is the “copy machine inside City Hall” – and what does it do?

11-27-12 Agenda

• Good things• Review cell parts• Protists notes• Reminder that progress reports go out on

Thursday, quiz on Thursday, field trip on Friday!

Protists…

Euglena, Amoeba, Paramecium, and Volvox

Protists…Animal? Plant? Fungus?

Protists are a mix of organisms that don’t exactly fit into the animal, plant, or fungus kingdoms…and sort of fits into all of them!

Protists are __________________ - which means they have a nucleus and other membrane bound organelles. The other category would be prokaryotic. What are we?

eukaryotes

Protists

• ____________________ - one celled organisms.

• Some have animal – like qualities (_____________ means “first animal” in Greek)

• Some have plant-like qualities like _______________

• Some are like fungi

Uni-cellular

Protozoa

Chlorophyll to use in photosynthesis

Protists – finding food

• Those who can feed themselves with photosynthesis are called ________________

• Those who must find food in the environment around them (or move to find food) are called ________________________.

Autotrophs

Heterotrophs

Protists - locomotion

• Some use a fake foot that they ooze outward to move, its called a … __________________

One example is the _____________________Amoeba

Pseudopod

Protists - locomotion

• Some have small, hair-like structures that come out of the membrane all over the organism… __________________

One example is the _____________________Paramecium

Cilia

Protists - locomotion

• Some use a whip-like tail known as a ____________________

One example of this is the __________________

Flagellum

Euglena

Protists - locomotion

• Some work with each other – combining flagella and teamwork…

One example is the _____________________Volvox

In your notebook• Go ahead and create this table on your own

paper.• Let’s talk about each of these protists and fill

in our new table.Species Locomotion Description Autotroph or

Euglena

Volvox

Amoeba• Some use a fake foot that they ooze outward to move, its

called a … __________________• Single celled or ___________________• They must find food in the environment so they are

________________________________• They reproduce through _____________ which means they

simply split into two cells.

HeterotrophsAsexual means most often, but sexual reproduction is possible, too

Euglena

• Some use a whip-like tail known as a ____________________

• Single celled or ______________________• Can either use photosynthesis OR collect food from

the environment so a ________________• Reproduces through _____________________

HeterotrophFission

Euglena

EUGLENA

Volvox• Some work with each other – combining flagella and

teamwork…• Volvox is actually many cells but each is an individual organism

– they simply live together in a colony for the ease of life.• Contain chlorophyll so must be _______________ but can also

collect NUTRIENTS from the environment so considered both ________________________________

Plant-likeAuto and heterotroph

Volvox• Each of the cells have two flagella and they must coordinate

them to cause motion for the entire colony.• They have a red “eye” spot that can help determine light.• They work together but seem to have poles (so they know

forward and back.• The volvox colony will reproduce new cells through asexual

reproduction, but also has the ability to go to sexual reproduction so two separate colonies would be needed.

Exit Slip

On the same paper from yesterday – continue with today’s exit slip!

1. Choose the wrong statement from the following.a) Mitochondria produces most of the energy for the

cell.b) Chloroplasts are “food producers.”c) Cell wall controls the movements of materials into

and out of the cell.d) Nucleus regulates and controls all cell activities,

acting as the “brain” of the cell.

2. Match the cell part to the nick name.1) Cytoplasm2) Nuclear membrane 3) Vacuoles

a. Gate of the nucleusb. Area of movement where cell parts movec. Storage tanks

3. This cell part that is surrounded by a nuclear membrane.

Is it a nucleus? YES or NO

4. This cell part is the powerhouse of the cell.

Is it a mitochondria? YES or NO

5. Are these chromosomes? YES or NO
